Should I get retested if I’ve already tested positive for COVID-19?

Retesting for COVID-19 is not recommended for individuals who have tested positive in the past 3 months. Individuals who test positive for COVID-19 within the past three months do not need to get retested unless they develop new symptoms. Available data indicates that individuals with mild-to-moderate COVID-19 are no longer infectious 10 days after symptoms start. Individuals with severe or critical illness, as well as those who have a weakened immune system, may remain infectious for up to 20 days after symptoms start. Individuals who have recovered may have detectable virus in their samples for up to 3 months after the start of infection, but may not be infectious during that time. If you have questions, cContact your healthcare provider for additional information on whether retesting is right for you.
